Serial No. 754,188.

This invention relates to'improvements in the method of transmitting andreceiving quotations and in the apparatus and circuit arrangementstherefor.

As is known by those familiar with the operation of quotation or otherticker systems, in the method heretofore employed for the transmissionof characters, the o erator, by the manipulation of keys on a key oard,controls the ticker transmitter directly by means of electrical circuitsfrom the various keys of the keyboard ;to the transmitter.- In thesystem herein described ,the characters to be transmitted are firsttranscribed by the operator by means of a keyboard perforator upon atape in telegraphic code and the perforated tape is thenfed through atape transmitter which, in"conjunction with a ticker transmitter,controls the'character impulses sent over 20 the lines to theso-c'alled,tickers at the brokers or other receiving ofiices.

I can best explain the I several features of my invention in connectionWiththe accom-' panying drawings in Which-Figures l and 2, takentogether, illustrate apparatus at'the transmitting and receivingstations for carrying out my automatic stock ticker transmission system;Fig. 3 is an illustrative diagram of the circuits connecting thecontacts of the tape transmitter with the segments of the selectorheads, the latter being shown in developed form; Fig. 4, shows a faceView of the selector heads; Fig. 5 shows the alphabet and figures asthey appear when punched in the tape in telegraphic code characters;Fig. 6 showsthe order or arrangement of characters on the face of thetypewheel of the ticker when developed; Fig. 7 illustrates aspecimen .ofa stock ticker tape; Fig. 8 illustrates the selection circuits for theletter Dig; 9 illustrates the-circuits for the letter Fig. 10illustrates the selection circuits on the two selector heads when thesame character is duplicated; Fig. 11 shows the circuits for the unisonfunction; Fig. '12 shows the circuits for the controlling of the shiftto letters or to figures; and Fig. 13 shows the circuits .for

operating the tape stepper function.

There are usually a number of ticker recorders on the same circultcontrolled'by a tinuously to print the market quotations upon therecording tape. The function of the automatic'system disclosed herein isto cause the ticker transmitter to stop at the correct point or positionin its rotation correspond in to the character which it is desired topr1nt,to hold it stationary for a definite interval, meanwhile preparingthe next succeedmg character selectiona'nd then releaslng thetransmitter and allowing it to rotate to the next character position. J

The essential features of'the self-winding ticker are shown in the lowerright hand por tion of Fig. 2. A type-wheel20, made in two sections, issecured to shaft 21.. One section of the type-wheel carries upon itsperiphery thirty lett'er characters and the other sectioncarries thirtyfigure characters, the characters on the two sections being in exactalinement,

The order in which the charactersappear on the type-wheel is shown inFig. 6. I have illustrated in Fig. 7 a section of stockticker tapeshowing how the market quotations appear on the printed tape as itleaves the ticker.

The type-wheel shaft 21 carries a pinion 23 in mesh with a gear 24,connected to a clock spring 25 which is maintained under constanttension "by the winding magnet 27, acting through the pawl 28 andratchet 29. The

shaft is prevented from continuous rotation by escapernent anchor 30,whichengages the teeth of escapement wheel 31. The escapewent anchor iscontrolled by the permanent magnet 32 and the coil 34. The reversals ofcurrent through the coil 34 cause the anchor to shift back and forth,each movement releasing the escapemcnt wheel and allowing the type-wheelto rotate an amount equal to the space of one character. As thetype-wheel must be rotated in this manner step by step to the characterwhich itis desired to print,

the escapement magnet coil 34 must receive as many impulses, alternatelypositive and negative, as there are spaces between the last characterprinted and the next character to be printed. The driving spring 25 ismaintained under approximately constant tension been rotated.

platens is a shift shift arm 37 rests betweenthe prongs of a fork 41 onthe upper end of pivoted armature W ers to run freely during threeorfour revolu the ticker 80 at regular intervals to insure their un1formv 42 of the shift magnet 43. If a letter character is to be printed, thearmature is moved to the right, thus throwing the shift arm 37 under theletters platen. When the press magnet 45 is energized'immediately thereafter,'the lever 40 carried by its armature 44 lifts the arm 37, whichstrikes the letters platen and presses the tape against the face of thetype-wheel, thereby printing the character to which the type-wheel hadpreviously If it is desired to print a figure character, the armature 42of the shift magnet deflects the arm 37 to the left, so that when-theprinting lever is raised, the figures platen presses the tapetagainstthe typewheel. After each character is printed, the tape is advancedthespace of one character on the down stroke of the printing lever.

The shift magnet requires a positive or a negative current impulse,depending upon respond to whether a letter or a figure character is tobe printed. It is necessary, therefore, to send over theline 50,positive or negative current to actuate the shift magnet and also tobreak said impulses into regular pulsations for the purpose of operatingthe winding magnet 27. The-pressmagnet, which is in the same circuitwith the escapement magnet responds to current of'either polarity butonly operates upon a long impulse and therefore does not the rapidreversals which actuate the latter. Henceon line 51, it is necessary to.send rapid reversals of current of suflicient number to cause thetype-Wheel to ro-- ta te to the character which it'is desired to printand then to prolong the last impulse of the group of reversals toenergize the press magnet and print the character; if

It is-ess ential that the typeewheels of alL tickers on a circuitv shallstartat the samecharacter, after which the type-wheels will rotate inunisonwith the escapement imr pulses passing over line 51. Tothis endthe type-wheel shaft 21 is provided with a worm 52, which is engaged bythe end 53 of an arm 54, pivotally mounted for vertical movement at 56in a post 57, Whichis rotatable on a vertical pivot in its support- 58.l/Vhen the shaft 21' has madethree revolutions withoutprinting acharacter, the projection 59 at the end of the worm strikes the end ofthe arm 54 and stops the rotation of the shaft." This always occurs whenthe .letters dot, just'bearm 37 carried by a' link 38, pivoted to'theprinting lever 40. The

' the relays of the the press magnet is raisedto print the unison dot,aforked arm 60, attached to the armature, lifts the arm 54, disengagingt from the stop 59 and permitting tbearm to be swung by its spring 61,back to in'itial position at the left of the worm. This releases th'eshaft 21 leaving it free to move step by step under the control ofthe.escapement impulses, This operation of allowing the tick- 'ity ofposition.

The line impulses are transmitted to the 3 self-winding ticker in thefollowing manner. At the transmitting station, eacli group of fromeightto fifteen tickers in a circuit, is operatedfrom a single set-ofrelays which are preferably mounted upon a circuit, panel,

several groups being controlled by a ticker, transmitter. As man circuitpanels are provided as ima'y'be ound necessary to divide thetickers'into suitable groups, butall of the circuit panels arecontrolled from the same transmitter.-

-;The essential features of ofFig. 1. The shaft 65, driven by a uniformspeed motor 66, carries a threeepoint cam -67, which c ontrols thewinding contact .68, and-through the gearing 69, drivesthefshaft 70' ataspeed fifteen times greater'than the speed of the shaft-65L Aneccentric7'1 on the shaft 70, operates a pole-changer tongue 72, which isconnected to positive battery. As it alternately engages contacts 73 and74- -connecte'dthrough conductors 75 and 76, re-

spectively, with the right and left hand coils of polar line relay 78,the \tongue 79 .of the latter follows its motion. left contacts of therelay 78 are connected to the ticker trainsmitter are illustrated in theupper portion" The right and the positive and negative poles of'the linebattery and hence as the armature 79 vibrates rapid reversals ofcurrent. are sent overihe line 51 to the escapement and press magnets ofthe tickers; The actuationof the escape mentmagnet'causes the type-wheelshaft-21 to revolve in unison with the incoming ,im-

ulses and consequently in unison with the 65 held stationary, thepole-changertongue 72 rests'on one or the other contact, thus holdingthe'armature 7 9 of thevpolar line ,relay on its corresponding contactand thereby sending out the required long impulse over the line 51. 4

The'point at which the ticker transmitter shaft shall be stopped isdetermined-by the location on the type-wheel of the character to beprinted. The tape transmitter T, which sets up the variops selections,is connected in such manner to the selector heads A and B of the tickertransmitter T, that the order of character selections on the selectorheads is the same as the order of characters on the ticker type-wheel.The selector heads are composed of insulated conductor segments. Theheadsare stationary, while the brusharms 80 and 81, which carrythebrushes, are carried by the shaft 65. When a character selection is setup in the tape transmitter, a circuit is established at only one pointinthe: rotation of the brushes, from ground in the tape transmitter,through certain segme'ntsiin the selector heads, through brush A ring,

A brush A}, through conductor 84' and stop will be describedhereinafter.

to operate the shift magnet 43 before the press magnet 45 actuates thearm toprint the character. I

The automatic control system which'causes.

the ticker transmitter to stop'at the correct point in its rotationcorresponding to the character which it' is desired to print, -wil1 nowbe described more in detail.

As is Well known by those familiar with telegraph apparatus, thequotations which it is'desired to transmit are prepared byan operator inthe form of a perforated'tapc by means'of a keyboard perforator having akey for each character appearing on the typewheel of the recorder orticker, each ch aractcr having a different combination of holesconstituting the character selection. In the present system, in additionto the character keys, I-employ' three function keys, the unison, the

tape and the rub-out, the operation of which magnets 85, ;ondu tor132mgpsitivehattery;g The width of the tape permits six holes to by way ofback contact and armature ofr'elay? .befp-erforated. Of these the tophole, which R The energization of the stop magnet 85, 1 causes the stoparm 86, carriedby its armature, to engage the end of the stop clip .87,

thereby stoppingthe rotation of both shafts 65 and 70.

As previously stated, the position of the armature 42, of the shiftmagnet 43, is controlled by transmitting either positive or negativecurrent over line 50, depending upon whether a letter or a figurecharacter s to be printed. This polarity is determined by the positionof the shift relay SR on the circuit panel. This relay is controlled bythe master shift relay 90, which controls the relays on all of thepanels, and the master shift relay in turn is' controlled by thecharacter selection in the tape'transmitter. i I

' It will be observed that the line 50 passes through the back contactand tongue or armature of the winding relay WR, before reaching thetongue or armature of the shift relay. When the ticker transmitterrevolves freely,

Y thecam 67 opens andcloses the winding contact 68 three times perrevolution of the shaft 65, thus causing the winding relay VVR toalternately attract and release its tongue or armature and in turncausing the winding magnet 27 to attract and release its armature,

thereby keeping the clock spring 25 'wound'to supply the driving forceto the type-wheel shaft 21. The circuit for the winding contact 68 onthe ticker transmitter passes through conductor 91 and contact 92 topositive battery, but this circuit is only closed when the stop magnet85 is deenergized and the transmitter shaft is revolving freely. \Vhenthe. stop magnet is energized to stop the transis designated the zerohole, is for the purpose of distinguishing between figures and letters..Theqz'ero hole is perforated on all figure characters and is notperforated for lett'er characters. The other five holes are for thepurpose of selection or determining the character to be printed' Theselection for all characters is shown in Figure 5.

The armature or tongue ofthe U After the perforated tape is prepared byl the operator, it is passed through a tape transmitter of the samegeneral type shown.

in U. S. patent to'Benjamin No. 1,298,440/

I have, however, made a number of changes and have embodied new featuresin orderto adapt it to my present purposes. The essential features ofthis tape transmitter are illustrated in the upper portion of Fig. 2.Six

reciprocable pins P arev employed, one for each hole in the tape, andeach pin controls -a rocker-arm 100, carrying two semi-flexiblesegments. The segments are so arranged that there are thirty distinctstop positions during one revolution of the brush arm. Face views of theselector heads are shown in Fig. 4. ,In the lower portion of Fig. .3, Ihave shown the segmented face of the heads in developed form and in theupper portion of the figure I have indicated diagrammatically the tapetransmitter tongues and cooperating contacts and have indicated theselector-head segmented rings to which the contacts are connected.

The tape transmitter tongues marked 1, 2,

e 3, Land 5, are theoncs which control the character selection and thestopping of the ticker transmitter. .The right hand set of tapetransmitter contacts is connected direct-. 'ly' to the segments of the,Aselector head,

and the left hand set of tape transmittercontacts is connected directlyto the segments of thefvB. selector head. The character'corresponding toeach set of segments appears on the diagrarnjust above the developedsegmented rings in Figure 3.

When a selection'is made in the tape transs mitter by certain of thepins I, passing through perforations in the tape indicated at T, thetongues-which correspond to the pms which passed throughtheperforations, are moved over against their marking contacts- M, whilethe other tongues remain against thei'rspacing contacts. Thisselectionor a'rrangement of'the tongues prepares a circuit which iscompleted by the brushes carried on the brush arms 80 and 81-as theycome to the set of segments corresponding to the selection set up. Thestop magnet 8 5 is energized by the completion of the circuitthrough itand 'causesthe stop arm 86 to arrest the rotation ofthe tickertransmitter shaft 65, with the brushes resting on't-he line of segmentsthe segments shown in Figure -8, are inthe correct relative position asthey-actually oo our on the selector head. Only'the right hand set oftape transmitter'tongues and contacts appear in Figure'8.

With the tape transmitter tongues in the position shown in Figure 8, andwith the ticker transmitter brushes on the line ofsegments'corresponding to the character slected, there is a circuit fromground on NO. 1 tongue of -the tape transmitter, through the tongues andcontacts of the tape transmitter,

connected as shown, to the segments and brushes of theticker transmitterand through stop magnet 85 to positive battery. This energizes the stopmagnet, which stops the transmitter shaft with the brushes resting onthe selected line of segments, thereby causing the tickers to print thecharacter selected in the manner previously described.

The selection for the letter Y is l, 3 and 5 marking. The circuits forthis selection are shown in Figure 9 and will be easily understood. Theselection for any character on the A selector head may be traced throughin a similar manner, first setting up the correct selection in the tapetransmitter, as shown in Figure 3, and then assuming the selector headbrushes to-be on the segments for that particular character.

It will be found from an examination of the diagram that there is onlyone position on the headwhere the revolving brushes complete a circuitto the stop magnet for anyone character set up inthe tape transmitter.Each character on the ticker type-wheel appears only once-on the Aselector head.

{Figure 4: is.=a face viewof the two selector heads. The brush arms 80and 81 are opposite each other on the shaft and consequent- I ly thebrush arm 80 is at-thetop of the A headcwhen the brush arm-81 is at thebottom of the B head. Furthermore as the heads face eachother, thebrushes will rotate thereon in opposite directions as indicated by thear-- rows. i

By referring to Figure 6 showing the developed face of the type-wheel itwillbeobservedthat there are two sets of figures 1 to 8 inclusive, twofigure-dots and three letter dots. It is desirable, of course, that theticker transmitter and consequently the tickers being worked from it,shall stop at the fi t one of the duplicate characters when thatcharacter is set up in thetape transmitter.

To accomplish this result, I provide the B selector head and the secondbrush arm 81.

The segmented rings of the B selector headare shown in developed form inFigure 3 and in the correct position with respect to the A selector headand the-brush arms In additiontothe duplicate figures and'dots, this Bhead has segments assigned to three functions, viz: the unison dot, thetape stepper, and the rub-out, the purpose of which willbe explainedlater. The left hand set of contacts in the tape transmitter isconnected to the B head, as indicated in Figure l 3. I Selections arethus made independently on the two selector heads, there being no commoncircuits, but the same selection is prepared for both heads at the sametime;

Theselection for the figure 4 is thesame. in the two positions, that is,0, 1,4 marking. It is obvious thenthat if thecharacter' 4 is perforatedin the tape a circuit willbe prepared when thebrushes reach the fifthposition on the A head and likewise in the sixteenth position onthe Bhead. The ticker transmitter brushes will there-fore complete a circuitthrough the stop magnet 85,in either position and the'brush arm will bestopped in .which ever positionit reaches first.

meaoea marking, is set up inthe tape transmitter,

. the ticker transmitter must stop only on the fifth position of theA-selector head and in 5 no other position on either head. The letter Dand figure 4 differ onlyiii'nthat the latter has an 0 perforation inadiitionio the 1, 1 perforations on tne tape. The means ofdistinguishing betweenthe nearlgytsimilar selections' for D and 4 canbesti ibeexplained by v reference to the liagrams \.of -Figure '10..

' Thev selection for the charaeber a; as set up in the tape transm ttershowman-Figure 10, the selection being 0, hfl igarki-ng. By tracing thecircuits, it Willffbe seen that the stop magnet 85, can be energizedeither in the fifth. or in the sixteenth position of the I brushes. If,however, the zero tongue of the tape-transmitter is on the spacingcontact, as for'the character D, in which the selection is 1, 1 marking,there is no circuit to the stop magnet in the sixteenth. position sincethe conductor. leading to the segment 12A is then open.

Similar circuits may be other duplicate characters; It will be observedthatthere is no circuit to the stop magnet 85 directly from the segmentsof the B selector head but that the selection circuits, after passingthrough this head, pass back to the zero tongue of thetape transmitterand then to the last ring on each selector head.

My method of shifting to either letters or .fig'ures in printing acharacter will now be described. A figure character is denoted by aholepunched'in the tape in the zero position in addition to "the holesdenoting the combination for that particular character. This eliminatesthe necessity of punching a special figure shift selection in the tapebefore the character selection as was done heretofore.

The circuits controlling the letters and figures shift are showntogether with the selec-,

, I anditsleft coil. traced for the tion circuits in Figure 2. Theposition ofthe zero tongue is controlled by one of the selecting pins Pso that when a hole is perforated in the tape at a zero position,thezero tongue is moved against its left hand or marking contact, andwhen there is no zero hole in the tape, the zero tongue rests upon theright hand or spacing contact.

The seventh tongue, which is shownas the upper tongaie, above the zerotongue, is not controlled by. any" selecting pin, but is mounted on arocker arm, (not shown) identical with the six pin controlled rockerarms 100, except that it is connected directly with the armature 108 ofthe operating ma net 110 and oscillates with it. When, therefore,

the magnet 110 is not ener izedthe seventh tongue rests on its'left banor marking'contact, and when the magnet is energized this contact. Alsoas the magnet is energized, the six selecting pins P are withdrawn fromthe tape, causing the selecting tongues to move" over against theirspacing contacts. This must be kept in mind in the followingexplanation.

Suppose a figure character is to be set up in the tape transmitter.passes through the zero hole punched in the tape and consequently thezero tongue is carried over against its marking contact as shown in.Fig. 12. Accordingly there is a circuit from ground on the seventhtrans- The zero pin then.

mitter tongue, through its left hand marking contact, to the left handcoil of theshift control relay 112 to plus battery. Its 'armature 112 ismoved to the left or figures contact 114, and energizes the left handcoil of the master shift relay through a circuit from ground througharmature 112, contact 114, and left hand coil of relay 90 to plusbattery. The shift control relay 112 also looks itself on the left sidethrough 3000 ohms The armature of the master shift relay 90, being movedagainst its left hand contact 117,*'does not energize the shift relaysSR on the circuit panels. Consequently these shift relays send out tothe tickers the plus polarity required to operate the ticker shiftmagnets 43 to the figures side.

The circuits for a letter character are similar to those just described,but in this, case the armature of the master shii relay 90 is moved overto its right hand contact 118, thus closing a circuit from plus battery,through armature 90, contact 118, shift relay SR to groundPThe armatureortongue of relay SR is thus drawn against contact 120, estab lishing acircuit through tongue of relay SR, tongue and back contact of relayVVR,-conductor 50, and coil of shift magnet 43-to ground. This impulsecauses the armature 42 to shift the arm 37 to the right under theletters platen.

When the tape transmitter magnet is operated to step the tape T?forward, the chcuit from ground in the tape transmitter to the shiftcontrol relay 112 is broken by reason of the seventh tongue being movedto i'tsspacing' contact. The locking current tlirou h the armaturetongue 112 however holds t e armature firmly on the side to which it waspreviously moved, until another operating impulse is received from thetape transmitter. This; locking'of the shift control relay 112 keeps onecoil'fof the master shift relay 90 always energized and insures goodoperation of the shift relays SR on the circuit panels. The ratio ofoperating current to locking is about three and one-half to one.

It is necessary to bring the ground conneccurrent in. the coils of theshift control relay tion to the zero tongue through the seventh or 9'erating tongue and it'smarking contact in 65 tongue is shifted overagainst its spacing etapetransmitter for threason that as the tape isadvanced, the zero tongue, together with the otherifive selectingtongues, is drawn over to the spacing contact between characterselections. Hence if ground was applied'directly to the zero tongue, theshift control re the letters side between consecutive figure;

characters. I have shown the connections, ground is not applied tothezero tongue until the tape transmitter magnet is de-energized and thesetting up of the selection is completed.

Upon starting to transmit. stock quotations, the type-wheels of allofthe tickers must be at the same point. The first chatacter to be ingfurther quotations.

' ticker transmitter.

121 to the armature 123 of the unison magnet 124, carries which carriesthe arm transmitted is the'unison dot whlch appears on the type-wheel infront of the letter A. At

definiteintervalsduring transmission of quotations the tickertransmitter must be allowed to run freely for four revolutions, therebycausing all tickers to rotate. to the unison point, and thenstarting'the operation again by first printing the unison dot beforeprint- When transmitting continuously straight quotations any one of thethree dots occurring before the lettersA,

J or S, may be rinted, depending upon the positionof the ast character.

The operation of the unison function is asfollows: Aspiral 65 is cut onthe shaft 65 of the An arm 119, pivoted at a pin 125 which travels inthe spiral 65 when the armature is retracted. With. every characterprinted, the unison magnet is energized, attracting its armature 119downward, withdrawing the pin 125 from the spiral and the spring 119starting position, thereby bringing the pin back to the beginning of thespiral. Whenno character is printed the ticker. transmitter shaft runsfreely and after four complete revolutions the pin has moved along thespiral until the arm 119 has closed the unison contact 126. All of thetickers have likewise-run to the unison position. The contact 126, inconjunction with the selection for unison, viz: 1, 2, 3, 4, 5 marking,perforated in' the tape and set up in the tape transmitter, prepares acircuit.which is completed by the ticker transmitter when they reach theline of segments corresponding to the unison dot. When this occurs thestop magnet85 is energized, stopping the shaft of the ticker transmitterand causing all tickers to print the unison dot. v

v The circuits involved in the operationof the unison function are shownin Fig. '11

andlalso appear as part of the entire system then'swing's the arm 119 toits tracted, the arm, 86 engages the brushes of illustrated in Figures 1and'2. It will be seen that although the unison-selection, 1-, 2, 3, 4,5

marking, is set up in the tape transmitter, the circuit cannot becompleted until the unison contact 123 is'closed, which only happensafter four free revolutions of the'ticker transmitter shaft. 'Thecircuit of the unison magnet 124 is closed by the side contact 130 ofcontrol relay R, and consequently the unison contact is kept open whenprinting other characters than-unison. Relay B does not operate on thetape,.st-epper function. Therefore the unison contact closes and re-"printedfoll'owing a group of tape-steppers.

The group of control-relays R R R I Rfltogether with the tape-stepperrelay R are shown with their circuits in the lower part of Figure 1.After the circuits correspond.- ing toany character perforated in thetape have operated through the tape transmitter tongues and contacts andthe .ticker transmitter selector heads and brushes to stop the tickertransmitter shaft with the brushes on the energized line of segments, itis necessary to advance the perforated tape the spaceof one center holethrough the tape transmitter, set up a new selection-in the tapetransmitter and release the shaft ofthe ticker transmitter so that itcan revolve to the line of segments corresponding to the next selectedcharacter. This,is accomplished by a sequence of operations of thecontrol relays.

When a selection is set up in the tape trans mitter and the brushes ofthe selector heads arrive at the correspondingsegments, a cir-SEQ-conductor 132, back stop and armature tongue of relay R to plusbattery. A

As the armature of stop magnet is atthe stop clip 87, thereby stoppingthe rotation of the ticker tranSmittershaft and the selector and causingthe selected character to print on the tickers. Asthe armature of thestop magnet moves towardthe magnet, it withdraws the 'w edge pin 88 andallows the operating contacts 89 to close. This establishes a circuit;from positive battery through operatingcontacts 89, conductor 1341, coilof relay It, left hand or locking coil' of relay R con- 1 ductor 135,tongue and'ba'ck contact of relay Rfi conductor 136 and tape transmittermagnet-110 to ground. Relays R and R and the tape transmitter magnet'110 are therefore energized simultaneously,'but relays R and TRZhQVlDgQIIO work to do, other than moving brushes their armatures,areoperated slightly in ad- I if lvan'ce of the tape transmitter magnet.

This allows thecharacter selection in the tape transmitter to be withdrawn and a newcharacter to be set up. The stop magnet being held in energizedcondition by the ground applied by relay R holds the shaft of the tickertransmitter stationary until the new character selection is prepared inthe tape transmitter.

It was noted that the tape transmitter mag net 110 is energized at thesame instant as relay R and the left hand, locking coil of relay R Thedownward movementof the arm 108 attached to the magnet armaturedepresses all of the selecting pins P, and causes all of the selectingtongues t to move over against their right-hand spacing contacts, thusbreaking up the character selection. The arm 108 also rocks the-lever143 and causes the star Wheel 145 to-advance the tape T, the distance.of one center hole, bringing the perforations for-the next succeedingcharacter over the selecting pins.

As previously explained, there is a seventh rocker arm (not shown) likethe rocker arm 100, which carries the tape transmitter tongues 7, andwhich is directly connected to 'the armature 108 so'that it moves withit.

The tongue-7 carried by this arm rests against the left hand ormarking contact when the magn'et 110 is de-energized and is shifted- Asthis tape )transmitter operating con 'tact closes, it establishes acircuit from ground through'tongue 7, right hand or operating contact00, conductor 146, automatic stop switch 150, conductor 151, coil ofrelay R conductor 152, coil of relay R conductor 134, operating contact89 on the ticker transmitter to positive battery. As the armature ofrelay R -i's attracted, it closes a.

side contact 140 which applies a locking ground to its own coil. Theoperating contact 0G in the tape transmitter may now be opened, but therelay R will remain energized untilits locking circuit is broken by theopening of the operating contact 89 on the ticker transmitter. Theclosing of the side contact 140 of relay R also energizes the unisonmagnet 124 through the already'closed side contact 130 of relay R lVhenthe armature of relay R? is attracted and engages its front contact, itcompletes a circuit from positive battery, through resistance 153,armature and front contact of relay R conductor 154, right hand orrelease coil of relay R conductor 156 and coil of relay R to ground. Theoperation of relay R breaks the circuit through 'its armature tongue andback contact, which had energized the tapetransmitter magnet 110. Theoperation of relay R also de-energizes the left hand or locking coil ofrelay RH This allows the current in theright hand or release coil toattract the armature to that side and removes the locking ground fromthe stop magnet 85. As the armature of the stop ma gnet falls backagainst its back stop, the

wedge gin 88 opens the operating contacts 89 which breaks the circuitthrough the coils of theirelays R and R allowing these relays release ofrelay R breaks the circuit through to return to their unoperatedposition. The

theleft hand or release coil of relay R and the coil of relayRfi Thetongue of relay R remains on its right hand contact while the tongue ofrelay Rfreturns to its back contact. All relays are now in their normalunoperated positions and are ready for a repetition of the same cycle ofoperations when the next character is printed. 1

The de-energizing ofthe stop magnet 85 also releases the tickertransmitter shaft, allowing the brushes to revolve .overthe selectorheads until they reach the line ofsegments corresponding to the nextcharacter Which has been set up in the tape transmitter.

If the new character thus set up in the tape 1 transmitter is the sameas the character which has just been printed, there will be a circuitfor this second character selection to the stop magnet through the sameline of segments'on thev selector head. Thisvcircuit is established forthe second character before the ticker transmitter brushes have left.the segmentupon which they had stopped for the printing of the previouscharacter. Hence when the locking ground is removed from the stop magnetby the movement of the tongue of relay R to its right hand contact underthe.

influence of the current inits release coil, as

tion brush. Relays R R R also remain energized.

It is necessary to release the ticker transmitter shaft and allow thebrushes to revolve until they reach the same character selection whenthey will be stopped andthe same character will be again printed.

As the tongue of relay R strikes its right hand contact, it completes .acircuit'from releasing the shaft and allowing the thrushes to revolveuntil ground through tongue and'back contact of relay R", tongue ofrelay R ,'conrluctor 157, coil of relay R conductor 158, front, contactand tongue of relay R, resistance 153to posi-. tive battery. Thisenergizes relay R and breaks the circuit ofgthe stop magnet, thus the.ticker transmitter they reach the lineof'segments of the same characterselection when they will be stopped and the second of, the repeatedcharacters will be printed. The release of the stop magnet opens theoperating contacts 89 and releases all of the relays as previouslyexplained. Although relay R receives impulses on all characters itsoperation'lis not required except when characters are repeated.

An arrangement of control relays can be provided in place of relay Rwhich will prevent the ticker transmitter shaft and the tickers beingworked from it from releasing when .a character is to be-rep'eated. Thisarrangement will cause the line 51 leading to the escapement magnet 34and the press magnet in the tickers to be opened and closed asmany timesas the character is to be repeated but does not change the polarityonline 51, and therefore does not rotate the typewheel. This causesthe'press magnet 45 in the tickers to be alternately released andattracted, another impression of the character being obtained each timethe magnet is attracted. The ticker transmitter shaft .and tickers arereleased and allowed to revolve only when a'different characterselection is set up in the tape transmitter. A diagram of theseconnections is not shown. as the method illustrated whereby thetypewheel is allowed to revolve between repeated characters isconsidered preferable.

The automatic stop switch is mounted on the base of the tape transmitterandis provided with a make and break contact 150 havmea'oaa ing-side butbeyond this no action can take place because the automatic stop switchis open. .WVhen .more tapeis perforated the switch is allowed to closeand the other con-. trol relays operate in sequence as previouslyexplained.

During a dull market when quotationsare few and are coming in atirregular intervals, it becomes necessary to advance the perforated'typewith one or more quotations on it from the perforatorto the tapetransmitterfor immediate transmission. As the tape must not be broken,there will be about three and one half inches of blank-tape between thegroups of quotations. This blank tape must he stepped through the tape,-transmitter in order to reach themext quotation but. i

the ticker transmitter and tickers must not be operated while it isbeing passed through.

The tape stepper character which is used between these separated groupsof quotations is a blank in the tape, that is, none of the holes areperforated and consequently circuits are shownin Figf binecl thoseportions which are in the tape stepper circuits.

Referring to Figure 13, the tape transmitter tongues are shown restingagainst the spacing contacts as for the tape stepper selBCtlOIL' Thespacing contacts of the left hand B set'are connected as shown to thetwo groups of tape ste )per segments onthe B? selector head. racing.through the selection circuit, it will be seen that there is a circuitfrom. ground in the tape transmitter through the contacts and segmentsand the brush C and conductor 160 to'the coil of tape stepper relay RThe circuit from the other side of relay R passes through conductor 138,back contact and tongue of relay R conductor 161, back contact andtongue of relay Rflito positive battery. Tape stepper relay. Ris'the'refore energized but the ticker transmitter is not stopped andprinted. i

Relay B when energized, locks itself in an operated position by applyinga ground connection to its coil through its armature no character istongue and front contact. The side contact I 162 of relay R is alsoclosed by. the armature and this closes a circuit to energize the tapetransmitter magnet 110, from positive bat" tery, side contacts 162,conductor 163, tongue and back contact of relay R conductor 136 to thetransmitter magnet and ground. The operation of this magnet advances thetape one center'hole through the tape transmitter.

At the end of the stroke of the armature 108, the transmitter tongue? ismoved against its. right hand contact OC, which I have designated theoperating contact, and this energizes relay R the circuit being fromground, through the seventh transmitter tongue, conductor 1 16,automatic cut-out 150, conductor 151, relay R conductor 152, co ductor155, left hand coil of relay R conduw tor 135, conductor 163, sidecontacts 162 of relay R to positive battery. The breaking of the circuitthrough the back contact and tongue of relay R releases relay R from theinfluence of its locking circuit and its tongue returns to its. backcontact. The opening of the side contact of relay R releases the tapetransmitter magnet 110 and also relay R All of the relaysare thusreturned to their unoperated position ready for the next tape stepperimpulse.

Exactly the same operation of relays takes place if the rub-outselection is set up in the tape transmitter. As there are two groups oftape stepper segments on the selector head, the tape can be steppedforward at a rate which is twice the free revolution' speed of theticker transmitter.

Although the impulse tlir-ctgh the right hand or locking coil of relay-Ris not suiticient to throw the tongue of the relay to that side, as ameasure of safety I bring the ground connection to the tongue of relay Bthrough the back contact and tongue of relay R Thus even if relay B doesoperate on the tape stepper function, it cannot'operate the tickertransmitter stop magnet as its ground circuit has been removed by theoperation of relay R.

While printing characters, the pins P are withdrawn from the tape andthe tongues t of the tape transmitter are moved over to their spacingcontacts each time that the tapeis stepped ahead. The tape stepperselection is thus set up momentarily each time that the tape is advancedbetween character selec tions. To prevent relay R from operating at thistime, the cireuit from the coil of relay 1%? is brought through the backcontact and tongue of relay R Relay R? operates for every printedcharacter and therefore relay R cannot be energized while printing istaking place.
